s Claims. (Cl. zs-ss) The present invention relates 'toanadjustableeyeboard to be used in conjunction with a slashing,warping,or other machine which will allow foror require the regulationof the width of the :Warp passing therethrough.

Normally when passing laments,threads, 'yarn or Ithe like, hereinafterdesignated as threads, from creels or other supply sources through anyof 'the machines previously mentioned, the threads, in order'to form aparticular width warp, pass through an eyeboard containing holespositioned in substantially vertical rows with the horizontal distancebetween the outermost holes defining the width of the warp desired. Eachvtime thata modification is desired either in the width ofthe warp with`the number of threads remaining the same or in the number of threadswith the width remaining the same, the operator is required to stop themachine, remove all of the threads being passed through the eyeboard,replace the eyeboard with a dilerent one having the desired number ofequally spaced holes for the desired width of warp, thread the neweyeboard and again put the machine into operation. The steps ofreplacing and threading-thefeyeboard have resulted in a considerableloss in operating time for the machine. In view of this loss ofoperating time the eyeboard of the present invention has been developedto substantially minimize the time required by the operator to obtainthe above referred to modifications.

Broadly, this invention provides an adjustable eyeboard composed of aplurality of sections which are movable to and from each othercontiguously in the same plane. More particularly, this inventionprovides an adjustable eyeboard comprising a frame having upper andlower channels therein, a plurality of sections having holes thereinslidably mounted in the channels, lost motion links connecting thesections and a turn buckle arrangement operatively connected to thesections to move them to and from each other.

It is therefore an object of this invention to provide a noveladjustable eyeboard which will allow for the regulation of the spacingbetween the threads passing therethrough and thereby the regulation ofthe width of the warp.

Other objects and advantages of this invention will become apparent fromthe following detailed description when considered in conjunction withthe accompanying drawings, wherein:

Figure l is a view in elevation of the eyeboard of this invention; and

Figure 2 is a sectional view taken along line 2-2 of Figure 1.

Referring to the drawings and more particularly to Figure 1, the numeralindicates an eyeboard composed of two end sections 11 and 12 and aplurality of intermediate sections 13. Each of said sections has holes14 therein through which threads pass when being conveyed from thecreels to the slashing machine. The holes 14 are so arranged in theeyeboard that they form a plurality of parallel rows departing slightlyfrom the vertical which ICC allow for more equally spaced threads vperunit Width of the warp.

End sections 11 and 12 and intermediate sections r'13 have top andbottom parallel sides 15 and 1'6, respectively. Intermediate sections 13also have parallel sides 17 and 18 which are parallel to therows ofholes passing through the intermediate sections and form an obliqueWiththe top and bottom parallel sides 15 and '16, respectively. Endsections 11 and 12 each have-a side 19 and -20, respectively, which areparallel to the rows of holes in'each section and the oblique sides 17and 18 of the intermediate sections. Positioned at the top and bottom ofsections 11, 12 and 13 are lost motion links 21 which interconnect thesections and define the maximum spacing between the sections.

Enclosing sections 11, 12 and 13 is a frame 22. Frame 22 is composed ofend members 23 v'and top and b'otto'm members v24 and 25, respectively.Bottom membe'r 25 is formed of three laminated plates V2'6, 27 and 28and compression plates 29 and 30. Plates 26 and 28 (as shown in Figure2) are of greater width than plate 27 so that upon being assembled theydene a channel in the bottom member 25 within which the lower portionsof sections 11, 12, and 13 may slide. The -top frame member 24 is formedof laminated plates 32 and 33, vanged plates 34 and 35, and compressionplates 36 and 37. As shown in Figure 2, iianged plates 34 and 35 aremuch wider than laminated plates 32 and 33 so that upon being assembledthey form a channel within which the lost motion links `21 and topportions of sections 11, 12land 13 may slide. v l

yAgain referring to Figure l, the means for'movi'n'g the sections to andfrom each other contiguously include sleeve members 38 and 39 attachedto the end-sections 11 and 12, respectively. Passing through sleeves 38and 39 is ashaft 40'having two'thre'aded portions thereon. Shaft 40passes through each of the sleeves in a threaded relationship so thatone threaded portion passes through the sleeve of section 11 while theother portion passes through the sleeves of section 12. The threadedportions of shaft 40 are oppositely threaded so that depending upon thedirection of rotation of the shaft the end-sections 11 and 12 will moveeither toward or away from each other. Supporting shaft 40 are endmembers 23 and support 41. Preventing longitudinal movement of shaft 40in the frame 20 are thrust shoulders 42 and 43 on each end of the shaftformed from a reduction in the diameter of shaft 40. Attached to theportion of shaft 40 extending beyond the frame members 23 by a. setscrew is crank 44 which upon being rotated results in the expansion orcontraction of the eyeboard.

With the parts constructed and arranged substantially as hereinbeforedescribed, the operation, briey stated, is as follows:

As shown in Figure 1 the eyeboard is in a contracted position butrotation of the crank will first move the end sections away from eachother followed consecutively by the outermost intermediate sectionsuntil the lost motion is taken up by the links whereupon the eyeboard isin its expanded position. Rotation of the crank in the oppositedirection will accordingly move the sections together.

By this invention operators without exchanging eyeboards may now changethe width of the warp and the number of threads going to make up saidwarp in a minimum amount of time and with a minimum amount of eiort.
